The Model 900 is equipped with a patented kinetic trough where water is dispersed uniformly across the pad. We provide a stainless steel valve seat where others do not.

Standard Features:

  • E1 Temperature Compensating Humidistat is included.
  • Bypass humidifier mounts easily on the warm or return plenum and delivers 17 GPD.
  • Evaporator pad replacement number GA19.
  • A portion of the heated air from the furnace passes through a water-soaked pad where it absorbs additional moisture and then returns for distribution throughout your home.
  • Water is metered into a patented kinetic trough and dispersed uniformly across the pad. Unevaporated water drains from the bottom of the unit to eliminate mineral build-up.
